US community gardens embody a conundrum: vital to community well-being and integral to urban social infrastructure, yet profoundly vulnerable through insecure land tenure, fragmented policy support and systemic disinvestment. This reflective essay examines the Philadelphia Garden Data Collaborative (PGDC), a multistakeholder initiative documenting, protecting and advocating for community-managed green space, from the authors' position as participant researchers. It traces the shift from grassroots mapping to coordinated data stewardship, which enabled both emergency interventions (such as preventing sheriff-sale evictions) and long-term preservation strategies, and examines the ethical dilemmas of collecting sensitive community data where bureaucratic neglect has rendered gardens invisible and where visibility can expose them to new risks. It concludes that data can strengthen advocacy and inform policy, but must be coupled with secure tenure mechanisms and sustained public investment.

A qualitative case study comparing the motivations, operational dynamics, land access challenges and legislative contexts of urban agriculture in two contrasting cities — Cape Town (South Africa) and Norton (Zimbabwe) — through stakeholder interviews and policy analysis, guided by social capital theory. In Cape Town urban agriculture is semi-institutionalised, backed by governmental and civil society actors and framed within wider food justice and community development agendas, yet practitioners face significant constraints from land access, urban policy fragmentation and competition over space. In Norton it is largely informal, a survivalist response to persistent socio-economic hardship with minimal formal support but relatively flexible regulation, where land-tenure insecurity and the threat of eviction are the pressing concerns. The paper argues that context-specific legislative frameworks, secure land rights and inclusive urban planning are the enabling conditions, situating urban agriculture within debates on land governance and urban informality.

Kissoly L. · Frontiers in Sustainable Food Systems · タンザニア・ダルエスサラーム

An exploratory qualitative case study and policy analysis of urban agriculture's current landscape and possible futures in rapidly urbanizing Dar es Salaam, drawing on targeted literature and document review, a policy and regulatory scan, and 52 key informant interviews with municipal actors, urban farmers and food-system practitioners conducted between April and September 2025. Urban agriculture is valued for household food supplementation, small-scale income and fresh-food provisioning through short-cycle vegetable production close to consumers, but remains shaped by tolerated informality, insecure land access, fragmented regulation, contamination risks, weak institutional coordination and pressure on peri-urban land. Five evidence-informed trajectories are proposed — managed river-corridor cultivation; sacks, buckets and roofs for dense-ward micro-production; institutional land clusters; peri-urban foodshed belts with circular-resource hubs; and small-scale aquaculture with insect-based feed — presented explicitly not as tested feasibility models but as differentiated options requiring further technical, environmental, spatial and economic assessment. The paper argues the future depends not on a single large-scale model but on risk-sensitive, institutionally grounded forms of support.

Much Faisal Syaputra · Jurnal Administrasi dan Kebijakan Publik · Indonesia (Makassar City)

This qualitative case study critically examined the governance structure of Makassar City's Lorong Wisata program, which integrates urban farming for food self-sufficiency. The study found a fragmented governance network dominated by the municipal government's vertical authority, with weak cross-sectoral collaboration, particularly with universities and private actors. Institutional fragility was evident due to the absence of functional task forces, leading to symbolic rather than substantive coordination.

Assyifa Fauzia, Evi Frimawaty, Hadi Susilo Arifin · RISALAH KEBIJAKAN PERTANIAN DAN LINGKUNGAN Rumusan Kajian Strategis Bidang Pertanian dan Lingkungan · Indonesia (Jakarta)

This study aimed to provide recommendations for community-based urban agriculture sustainability in Cempaka Putih District, Central Jakarta, facing challenges like limited land and environmental changes. Using SWOT analysis and FGDs with stakeholders, the findings indicate that strategies can be implemented through agricultural technology and strengthened collaboration. However, the study implies that supporting policies, incentives, investment facilitation, and continuous infrastructure and assistance are currently lacking for implementation.

Francis Mwaijande · African Journal of Empirical Research · Tanzania

This study, using a mixed-methods approach with 600 respondents from urban and peri-urban farmers and agri-food supply chain producers in Tanzania, confirmed urban agriculture's contribution to food availability, accessibility, stability, and utilization. However, it found that urban agriculture is not well-integrated into urban food and poverty reduction policies in Tanzania and is practiced without legitimate policy and legal frameworks. This policy gap indicates an inadequate policy enabling environment for urban agriculture to enhance food security.

Firdavs Berdikulov, Iroda Orifjonova, Bekhzod Eshboev, Jumanazar Xolmurzayev, Bakhtiyor Abdusayitov · Springer Link (Chiba Institute of Technology) · Uzbekistan (Samarkand)

This study examined agricultural growth in Samarkand, Uzbekistan's peri-urban regions from 2000 to 2024, using government data and predictive modeling. It found that urban populations surged while arable land declined, and the vegetable surplus, though currently meeting demand, began shrinking around 2015, suggesting a tipping point toward shortages. The research indicates that without proactive measures like smarter land allocation and advanced irrigation, Samarkand risks a structural food deficit within a decade.

This study investigated the emergence, legitimization, and survival of alternative food systems in low-income settlements across Latin America and the Caribbean. Researchers conducted 340 interviews and 312 questionnaires, following 18 bottom-up initiatives related to food production, distribution, transformation, and consumption in urban and peri-urban areas of Colombia, Cuba, Ecuador, and Chile. Empirical results demonstrated the inadequacy of existing regulations and policies to comprehend the dynamic resistance occurring in the "in between" spaces of both identities and urban structure.

Francisco Tomatis, Ana Marí­a Bonet de Viola, Ulises Reno, Ouiam Fatiha Boukharta, Luis Manuel Navas-Gracia · · Argentina

In Argentina, public policies like the Argentine Plan Against Hunger and the ProHuerta Program have stimulated urban agriculture to address the food emergency crisis in early 2024. Despite urban gardening being recognized as a crisis-addressing strategy, the existence and future forms of public policies supporting urban gardens remain uncertain amid recent national political changes. Several barriers to integration and consolidation of these programs are highlighted.

Akuto Akpedze Konou, Kossiwa Zinsou-Klassou, Pablo De Roulet, Armel Firmin Kemajou Mbianda, Jérôme Chenal · Land · Togo

This study in Greater Lomé, Togo, interviewed 11 experts and surveyed urban farmers to compare their perceptions of urban agriculture and health. The findings reveal a disconnect: urban farmers identify various challenges, including health-related difficulties, while experts tend to assume different health concerns, highlighting a misalignment between the perspectives of planning and design experts and urban farmers.

Cindy Vong · Journal of Food Law & Policy · Global

This Note argues that municipalities in the United States should permit on-site slaughter of backyard chickens on private residential property. Historically, local governments codified the separation of residential and agricultural uses, leading to bans and restrictions on urban agriculture. The current regulatory vacuum for urban agriculture creates conflicts and uncertainties, and allowing backyard slaughter could strengthen local food systems and regulate a growing urban practice.

Ylva Wallinder, Maria Langa · Environmental Sociology · Sweden

A study investigated the consequences of institutional policy change on urban gardening practices in Swedish municipalities over the last decade. Local sustainability policies have led to an increasingly business-centered model, which clashes even with entrepreneurial gardens. This shift caused associational gardening to give way to an extended focus on entrepreneurship and food production, representing a "green rationalization" of gardening practices in urban sustainability policies that hinders their sustainability potential.

A. Bayat, H. Govera · Suid-Afrikaanse tydskrif vir landbouvoorligting/South African journal of agricultural extension · South Africa (Cape Town)

This study descriptively investigated the vulnerability to shocks and pressures of the Philippi Horticultural Area (PHA), a key urban food-producing region in Cape Town, South Africa. Data were collected through surveys with stakeholders from government, the private sector, NGOs, private individuals, and informal settlers. Key findings revealed insufficient governance commitment, a lack of multi-stakeholder collaboration, and the growing threat of urban development on agricultural land.

Mohammed Adem Ali, B. Lilly Grace Eunice · Discover Sustainability · Ethiopia

Urban agriculture in Ethiopia is a vital livelihood strategy, contributing to employment, income, and food security. Despite its significant contributions to GDP and urban employment, its potential is insufficiently utilized due to structural obstacles. These hurdles include restricted access to land and water, deficient regulatory frameworks, poor institutional support, social stigma, and environmental risks, and it is insufficiently acknowledged in urban development strategies.

Moçambique MANI TESE, Franscisco Monteiro Chimote, Paulo Xavier Tebulo · Revista fisio&terapia. · Mozambique

A study conducted in Quelimane, Mozambique, analyzed the procedures and challenges for ensuring advocacy for sustainable food systems. The research highlighted institutional fragmentation, the absence of urban agriculture regulation, and precarious logistics as critical obstacles. While community micro-strategies and urban gardens were identified as potential catalysts for transformation, the study concluded that strengthening local governance and multi-sectoral mobilization are fundamental.

Chiara Tornaghi · · Global

This chapter, based on 15 years of research, identifies key shortcomings in urban planning policy that prevent urban agriculture from reaching its full potential for human and non-human health. These include the failure to recognize urban agriculture as food production, the invisibility of soil and its role, and the neglect of soil care and food production specialists in public land design and soil management. The chapter suggests that agroecological considerations can enhance urban agriculture's ambition in public spaces.

Koenraad Danneels · Landscape Research · India (Bangalore)

This paper responds to a critique regarding urban agriculture (UA) and urban planning in Bangalore, India, between the 1950s and 1970s. While urban agriculture is recognized as an emancipatory driver with economic, social, and physical benefits for urban dwellers, the abstract indicates a critical perspective on its promotion.

Jennifer Temmer, Alison Blay‐Palmer, Andrew Spring · Canadian Food Studies / La Revue canadienne des études sur l alimentation · Canada (Northwest Territories)

A Participatory Action Research study in Kakisa, Northwest Territories, applied the Community Agroecological Values Framework to food system planning. While the community successfully leveraged extra-regional resources by building relationships with organizations outside the territory, findings indicated that unstable relationships and conflicting perspectives regarding land use and agriculture constrained access to critical regional supports, including gardening knowledge networks, funding, and training opportunities. This study highlights the necessity of both short-term regional support and long-term local capacity building for sustainable food production.

Stella Kasiva Mbiti, Micah Makworo, Brenda Waruinu Githinji, Christine Sabwa · · Kenya

This study explored the inter-linkages of urbanization, climate change, and food insecurity in Kiambu Sub-County, Kenya. Findings show urbanization leads to dramatic land use changes, diminishing agricultural land, and exacerbated climate risks and food insecurity. The study identified institutional weaknesses, poor planning, limited regulatory frameworks, and political interference as key drivers of unsustainable urban growth and reduced food production.

José Arturo Méndez Espinoza, Martín Neri-Suárez, Karen Italia Ruiz-López · LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas) · Mexico (Puebla)

A case study in Cuautlancingo, Puebla, Mexico, revealed an adverse context for the reproduction of peri-urban family farming. Urban expansion, neoliberal policies, and real-estate speculation have displaced traditional agricultural practices and fostered land-tenure changes. Between 2005 and 2021, over 40% of agricultural areas were lost due to industrial and housing growth. The study concludes that without effective protection and territorial planning, peri-urban agriculture in Cuautlancingo is at risk of disappearing under urban and industrial pressures, with implications for local food security.

Ioana Florea · Environmental Sociology · Romania

This paper investigated three collective gardening projects in Bucharest that closed between 2019 and 2021, analyzing what remains of their sustainability capacities and commoning efforts after termination. Findings indicate that while essential commoning aspects like collectivity building and autonomy can endure and transfer to other spaces, cross-class aspects fade away with these transpositions. This reveals that what persists from closed gardening projects is strongly tied to structural historical contexts.

Sara Ramezani, Mahin Nastaran, Homayoon Nooraie, Kei Otsuki · Journal of Landscape Ecology · Iran

A study investigating urban agriculture land use changes in Damavand, Iran, from 1995 to 2022 found a 109% increase in built-up land and declines of 14.34% in barren land and 22.44% in vegetation, including urban agriculture lands. Interviews with 15 participants identified land value changes, attraction to urban livelihoods, management and planning factors, physical-environmental factors, and urban infrastructure availability as primary reasons for these changes. The research highlights the urgent need for effective planning to mitigate threats from extensive urban agriculture transformations.

Mahyudin Mahyudin, Muh. Akmal Ibrahim, Muhammad Yunus, Syahribulan Syahribulan · Journal of Management and Administration Provision · Indonesia (Makassar)

This research used a descriptive qualitative approach, including observation, in-depth interviews, and documentation, to analyze the implementation of development network policies for urban farming for sustainable food independence in Makassar City. The findings indicate that the implementation of the urban farming development policy network requires improvement through joint actions among stakeholders. This is due to a lack of instructors assisting the Women Farmers Group (KWT), which is the target of the urban farming program, thus affecting the sustainability of activities utilizing yard land for productive use and food independence.

A qualitative and quantitative study in Palmas, Tocantins, Brazil, aimed to understand the interfaces of the Palmas City Hall's community garden project. Based on ethnographic research, action research, and field study, the results showed that this local practice enhances community participation in urban garden planting in northern Palmas. It aligns with Sustainable Development Goals and is a viable tool for minimizing food insecurity and hunger reduction. However, the project requires structural adjustments, promotion of public and private partnerships, and support from universities and civil society for healthy sustainability.

This study aimed to analyze the Tangerang City government's role in implementing food security improvement programs and identify supporting and inhibiting factors. The research focused on an urban farming program with a 1,000-hole hydroponic system. A descriptive qualitative approach was used, with data collected through literature study and policy document analysis. Results showed the Tangerang City government acts as a regulator, facilitator, and coordinator. Supporting factors included clear regulations, provision of production facilities and technical training, active community participation, cross-sector collaboration, and hydroponic technology innovation. However, inhibiting factors included limited land, technical difficulties in technology adoption, limited resources, and low community adaptation to new innovations.
